Hello Randy
I have been installing Easy Heat (Warm Tiles)systems for about 10 yrs and no there is no training, however they do have excellent customer service ( based in Waterloo Ontario)I have never used Nu-Heat due to the much higher material costs for custom mat sizes.To many angles and offsets in the bath areas that I do to be able to use Nu-Heat's regular mat sizes.
My supplier says they are looking at a new product which is like Nu-Heat but you can cut it if needed.Won't be available till the new year.
I have 5 Easy Heat units to install in the next 3 to 4 weeks if you would like to see how they are done.I am in the Barrie area if you would like to set something up.
Randall
